    Movable aerodynamic blades of the compressor stator was one of the ways to improve the operation of the turbojet engine. General Electric has been considering for almost a year – Which concept to choose? In 1952, it was decided to use movable steering wheels. With this arrangement, it was easier to develop lubrication and sealing…

    Aleksander Mikulin, in addition to the large AM-3 engine, also developed the AM-5 engine with a lower power. This task resulted from the collapse of the TR-3 engine program, which had high hopes. The fall of the TR-3 engine program also plunged airframe programs, including the supersonic Su-17 (the first program with such a designation).…

    The number of new CCCP turbojet designs in the period 1946-1947 was large. However, they all had a major disadvantage – the extremely short flight time, and therefore a short range. Even for the frontline planes, these parameters were difficult to accept. In the UK and the US, the performance was much better. Therefore, in…

    During World War II, the CCCP paid little attention to the development of turbojet engines. The breakthrough came at the end of the war, when the Russians obtained several copies of the German Junkers Jumo-004 and BMW-003 engines, and some of the results of the experiments. Stalin ordered these engines to be copied and to…

    In 1957, the Aviation Structures Center No. 2 (OKL) was established at the WSK PZL Mielec plant, headed by Eng. Stanisław Jachyra. The team’s first project was the M-1 single-seat aerobatic plane. The letter "M" stands for Mielec. Ultimately, the M-1 was not built. In 1957, OKL received an order for a two-seater training-training aircraft…

    On June 23, 1958, the PZL M-2 training plane was tested in Mielec. The plane was to go to the Aeroclubs. In 1958, three copies were built. It turned out, however, that the plane, having a fixed, three-support landing gear, with a tail wheel, was not very suitable for training at the Aeroclub. Why? In…

    The experience of the Second World War has shown that missiles are an extremely effective weapon. Already during this war, the CCCP combat aviation used unguided missiles. The first anti-tank guided missiles were developed by Germany at the end of World War II. A certain amount of these missiles ended up in the hands of…

    In 1965, the CCCP did not have a mid-range air-to-air guided missile at its disposal. The missile was intended as the main armament of the newly developed MiG-23 aircraft. The new missile was generally to correspond to the American AIM-7 Sparrow missile. The task of building such a missile was entrusted to the design office…
